Abstract (en)
[origin: EP0409447A2] A fiber optic coupler is formed by providing a glass tube (10) having a longitudinal aperture (11) extending therethrough. Protective coating (21) is removed from a region of a first optical fiber (17) intermediate the ends thereof. Protective coating (22) is removed from an end region of at least one other optical fiber (18). The coated portion of the first fiber (17) is threaded through the tube (10) until the uncoated region thereof is near the tube end. The uncoated region of the second fiber (18) is placed adjacent that of the first fiber, and both uncoated regions are simultaneously fed into the tube aperture. After the threading operation has continued until the uncoated regions extend through the midregion (27) of the tube (11), the midregion is heated to collapse it about the fibers, and the central portion of the midregion is drawn to reduce the diameter thereof over a predetermined length.
